I had a couple a codes for my 1996 Nissan maxima.. A/F Sensor 1Bank 1, O2 sensor 1B1, Knock Sensor, EGCR solenoid/valve, and the EVAP Canister Purge Volume Control Valve. The car once turned on without being used for a couple of hours will idle fine, until you drive it for 20 minutes it will start to loose power and if you come to a stop it will die on you. I'm wondering which one of these is the main problem or do I have to change all of them..
